Thinking about lusting over "exotic" SMP systems back in the day and how one would have to go to such trouble to have a system that could multitask. Then thinking about many years later being effectively stuck on a quad core when I really wanted more threads for video encoding tomfoolery. Now, finally, there's enough CPU for everyone. It's nice.
I mean to be fair there's been enough CPU for a good few years at this point but it's still worth appreciating.
